Local and state law enforcement officials in Texas are facing ferocious criticism for why it took so long for officers to confront and stop the Uvalde shooter inside a fourth grade classroom.

The big picture: The shooter was inside the school for around 80 minutes before law enforcement stopped his attack, which killed 19 kids and two teachers.

The timeline, provided by Steven McCraw, director of Texas Department of Public Safety, on Friday.

McCraw said the shooter fired "at least 100 shots" throughout the attack.

What they're saying: Rep. Joaquin Castro (D-Texas) called on FBI director Christopher Wray to investigate and put together a timeline of the events in Uvalde after state authorities "provided the public with conflicting accounts that are at odds with those provided by witnesses."

The bottom line: After two days of providing often conflicting information, investigators said that a school district police officer was not inside the school when Ramos arrived, and, contrary to their previous reports, the officer had not confronted Ramos outside the building.
